    What kind of mileage can you expect(ruff ball park) from a 5.7 and 6.0?(not mpg)

    I know diesel's will run for ever if you take care of them, so i am comparing to that.

    I have a 97 K2500. Ext Cab, Long Bed. 8600 GVWR, 4.10 gears. Vortec 350 / 5.7L for you metric guys. 5900# curb weight. I can count on about 13 just banging around. I can squeeze 16 on the road if I'm really careful. I need to put in a tune, hopefully pick up some economy there. Truck has 135K on it.

    Hi Rich
    There are many chevys out there with the 6.0 that the guys are getting 150K out of them if you take care of them.

    Regards Mike

    Sorry, vehicle mileage. 200K+ is very common, 250K not unusual. I plan to get at least that out of mine. I have a friend with a Sub with 350K on the 350.

    Thanks Mike

    All the trucks I am seing in my price range are in the low 100,000 mile range, so maybe I will start looking at diesel( I want to buy something that will last awhile

    My 2500 with the 6.0 just rolled 150K today and not one single sign of letting down. Still pulls a trailer daily and plows all winter. My Blazer has 140K on the 350 and still gobs of power. And neither engine burns anything nor leaks a drop. It is all about the maintenance you give them. My 94 2500 had a 350 in it. Had 200k when I sold it, original engine with no overhaul. Still see it around town now with well over 300K and still running original and strong. And the 4L80E is still original behind it too

    My 98 has the 5.7. Somewhere around 175k miles and way to many idling hours with no major problems, just normal wear items and intake gaskets. Still has plenty of power, I figure it's good for 300k+ at this rate.

    I'm also looking at another 98 with a 5.7 with 156k on it, miles don't worry me one bit.

    Not so sure on the 6.0 for longevity, but if you get something with a 5.7 and just keep basic maintenance going on it and it will out last the truck. I've seen the inside of a 97 or 98 vortec 5.7 with 168k on it, no wear lip on the cylinders and still could see all the cross hatching. And it came out of a landscapers dump truck his employees drove. So you know a small block in a 1ton mason dump driven by employees got the crap beat out of it.

    I agee. Bought the Tahoe with 150K. Looked at one with 180K, Kind of wish I had bought that one. EFI makes these engines last so much longer.

    Both of my current trucks have the 5.7L engines in them,... the '90 dually-dumpbed is at about 213K,... the '92 is at 283K,... and both run prefect, neither one burns or leak any oil, they both fire right up at -30°,... and neither one has had the engines touched yet,... outside of regular maintenence. I had one other Chevy with the 4.3L in it, which is basically a 5.7L with 2 cylinders chopped off,... and sold that truck with 287K on it about 9 years ago,... saw it today again,... and the current owner told me last year he hadn't touched that engine either yet,... not sure on the mileage, but I'm sure that by now, it's well over 300K. IMO, that's a testimony, at least in part, to Amsoil.

    On the other hand I had a 1990 that never made it to 15000 miles when engine burned so much oil it had to be replaced under warranty. That is not the norm. Right now we have a 5.7 with 147000 and runs great.

    My 00 6.0 will turn 125k miles in the next week or so. Zero issues, bought it with 91k. Take care of it and it won't let you down.

    GM said the Vortec 6.0's are designed to run 250,000 at least

    I had a 93 1500 and sold that with about 300,000 on it and not a single problem with the engine or tranny, just replaced the starter once. That had the 5.7 Now I have a 96 1500 with 162,000 on it with the 5.7 and that thing still have plenty of power. In my opinion you can't go wrong with the 5.7!

    I have over 164K on a 2002 6.0 both engine and transmission show no signs of letting me down any time soon. All I have done is change the engine oil every 3-5K usually before the light comes on.
    I change the transmission oil and filter every fall, and I do just the ATF every spring

    At this point I would expect 300,000 out of this engine and tranny no problems

    I've run 2 6.0's to 230's. Change the oil and they're bulletproof! JMO

    Guy I work with has a 97 350 Z71 with 260,000. He bought it with 220,000, and has only done the intake gasket. One truck at work that came in for a check engine light, was a 5.3 1500 with 370,561 miles.
